Abstract

An array substrate and a display device are disclosed. The array substrate (01) comprises a gate electrode driving circuit (10), the gate electrode driving circuit (10) includes at least two stages of shift register units (SR1-SRn), and each stage of the shift register units (SR1-SRn) is connected with a row of gate lines (Gate1-Gaten). The shift register units (SR1-SRn) include driving modules (D1-Dn) and logical modules (L1-Ln); the driving modules (D1-Dn) include a portion located in a display region (100) of the array substrate.
